RELATED APPLICATIONS

This application is a continuation-in-part of U.S. patent applicationSer. No. 11/827,361 filed on Jul. 11, 2007, and claims the benefit ofand priority thereto under 35 U.S.C. §§119, 120, 363, 365, and 37 C.F.R.§1.55 and §1.78, incorporated by reference herein.

FIELD OF THE INVENTION

This subject invention relates to a therapeutic, fitness, and sportsenhancement device.

BACKGROUND OF THE INVENTION

Conventional cylindrical foam rolls are often used for tissuemobilization, improving body core strength and balance training. Whenused for tissue mobilization, the user typically lies or sits on thecylindrical foam roll and moves back and forth to mobilize target softtissue. The benefits of soft tissue mobilization include, inter alia,decreased muscle soreness, relief from joint stress, decreasedneuromuscular hypertonicity, increased joint range motion, extensibilityof musculotendinous junctions, increased neuromuscular efficiency, andmaintenance of normal functional muscle length. These benefits enhancerecovery of injuries and also maximize sports performance and result inimproved fitness.

However, the completely cylindrical shape of a conventional foam rollminimizes the effect of tissue mobilization. Moreover, such a designoften results in the user falling off the cylindrically shaped foamroll, which is aggravating and cumbersome.

When used for body core strength and balance training, the usertypically stands or on the cylindrical foam roll device to enhancebalance, coordination and core strength. However, because the user caneasily fall off the cylindrical shaped foam roll, the effectiveness ofthe body core strength and balance training session is often minimized.

Smaller sized cylindrical foam rolls may be used to mobilize small softtissue structures, such as the foot, plantar fascia, heel, Achillestendon and associated calf tissue, elbow, wrist, knee, head, neck, andthe like, to assist in the recovery of plantar fasciitis or similar typeailments.

However, conventional smaller sized cylindrical foam rolls are typicallyineffective at mobilizing the soft tissue of small soft tissuestructures because they cannot effectively break up collagenous fiberstherein.

Conventional foot massaging devices and patient positioning devices areknown which may include rolls with projections or cone shaped rolls.See, e.g., U.S. Pat. Nos. 2,039,495, 5,359,739, 5,411,470, and6,764,456. However, the rolls and devices disclosed therein are limitedto a one diameter, one density, and a one type of shape of theprojections and thus fail to effectively mobilize soft tissue structuresof the human body.

In other designs, theplurality of shaped projections 14 may extend over body 12 in anindividual pattern as shown in FIGS. 9A and 9B. Each of the plurality ofshaped projections 14, FIGS. 1-9B, preferably radially, extends about ⅛inch to about 3 inches from body 12, e.g., as shown by r-70, FIG. 2. Inone example, “soft” device 10, FIGS. 1-3, may include eleven projections14. In another example, “soft” device 10, FIG. 10, indicated at 41, mayhave twelve projections 14. In other examples, device 10 may have as fewas 6 projections or as many as 20 projections 14, although device 10 mayhave any number of projections of various shapes, disclosed above,depending on the therapeutic use of device 10.

In this example, often referred to as “firm” device10, the density of the pliable material of body 12 is in the range ofabout 2.0 lb/ft² to about 12 lb/ft³, e.g., preferably about 4 lb/ft³.The diameter, d-27, FIG. 2, of body 12 is in the range of about 3 inchesto about 8 inches, e.g., preferably about 3.5 or 7 inches. The length ofbody 12, length l-31, FIG. 3, is in the range of about 2 inches to about36 inches. In one preferred example, body 12 has a diameter of about 3inches and a length of about 8 inches. In yet another example, body 12has a diameter of about 3.5 inches and a length of about 12 inches. Inyet another example, body 12 has a diameter of about 7 inches and alength of about 18 inches. In another example, body 12 has a diameter ofabout 7 inches and a length of about 36 inches. Similar as discussedabove, the plurality of shaped projections 14 have a predeterminedshaped as discussed above with reference to FIGS. 1-10 and preferablyradially extend about ⅛ inch to about 3 inches from body 12. FIG. 10shows on example of “firm” device 10, indicated at 43. In this example,projections 14 may have a triangle shape as shown. In this design,device 10 has about thirteen projections 14, although device 10 couldhave any number of projections of various shapes, discussed above,depending on the therapeutic use of device 10.

In yet another example, the one or more of density of body 12 and thediameter of body 12 in combination with the shape of projections 14 arepreferably chosen to mobilization soft tissue structures of the humanbody which may include, inter alia, the Quadriceps, Hamstrings,Rhomboids, Upper Trapezius, Forearm, Rotator cuff, Glutes, Piriformis,Calf, Feet, Head and Neck. In this example, which may be referred to as“hard” device 10, the density of the pliable material of body 12 is inthe range of about 4.0 lb/ft² to about 12 lb/ft³, e.g., preferably about6 lb/ft³. The diameter, d-27, FIG. 2, of body 12 is in the range ofabout 3 inches to about 8 inches, e.g., preferably about 3.5 or 7inches. The length of body 12, length l-31, FIG. 3, is in the range ofabout 2 inches to about 36 inches. In one preferred example, body 12 hasa diameter of about 3 inches and a length of about 8 inches. In yetanother example, body 12 has a diameter of about 3.5 inches and a lengthof about 12 inches. In another example, body 12 has a diameter of about7 inches and a length of about 18 inches. In another example, body 12has a diameter of about 7 inches and a length of about 36 inches.Similar as discussed above, the plurality of shaped projections 14 havea predetermined shaped as discussed above with reference to FIGS. 1-10and preferably radially extend about ⅛ inch to about 3 inches from body12. FIG. 10 shows an example of device 10, indicated at 45. In thisexample, device 10 may include about seven projections with a curvedshape as shown, although device 10 may have any number of projections ofvarious shapes, discussed above, depending on the therapeutic use ofdevice 10.

In the examples above, one or more of the predetermined density and thepredetermined diameter in combination with the predetermined shape ofthe projections effectively mobilize soft tissue structures of the humanbody. In other examples, one or more of the predetermined density andpredetermined diameter in combination with the predetermined shape ofthe projections may be chosen to effectively optimize body core strengthand optimize balance training and/or efficiently break up collagenousfibers of soft tissue structures and/or enhance flexibility of softtissue structures and/or enhance distensibility of soft tissuestructures. Moreover, projections 14 stabilize device 10 when used forbody core strength and balance training.

Examples of the operation of therapeutic, fitness and sports enhancementdevice 10 with projections 14 of one or more embodiments of thisinvention used to mobilize soft tissue structures of the human bodyand/or effectively optimize body core strength and optimize balancetraining and/or efficiently break up collagenous fibers of soft tissuestructures and/or enhance flexibility of soft tissue structures and/orenhance distensibility of soft tissue structures are shown in FIGS.11A-11M. For example, FIG. 11A shows an example of device 10 being usedto mobilize the soft tissue of Quadriceps 98. When moved back and forthin direction 100, projections 14 extend into the soft tissue ofQuadriceps 98 and mobilize Quadriceps 98. This breaks up the collagenousfibers of the Quadriceps 98, enhances flexibility and enhancesdistensibility of Quadriceps 98.

In other examples, therapeutic, fitness, and sports enhancement device10 may be used in a similar manner as discussed above with reference toFIG. 11A to mobilize soft tissue structures of the Iliotibial band(ITB), as shown in FIG. 11B, the inner thigh, as shown in FIG. 11C, theGlutes, as shown in FIG. 11E, the Piriformis, as shown in FIG. 11F, theHamstrings, as shown in FIG. 10G, the Lumbar region, as shown in FIG.11H, the Rhomboids, as shown in FIG. 11I, the Thoracic region (Mid/LowerBack), as shown in FIGS. 11J and 11K, the Shins, as shown in FIG. 11L,and the calf, as shown in FIG. 11M.

Examples of the operation of “firm” and/or “hard” therapeutic, fitness,and sports enhancement device 10 used to mobilize soft tissue structuresof the human body, break up collagenous fibers and/or enhanceflexibility and/or enhance distensibility are shown in FIGS. 12A-12I.For example, device 10 may be used to effectively mobilize soft tissue,break up collagenous fibers and/or enhance flexibility anddistensibility of the Neck, as shown in FIG. 12A, the upper Neck, asshown in FIG. 12B, the upper Trapezius, as shown in FIG. 12C, theshoulder and Rotator cuff, as shown in FIG. 12D, the Rhomboids, as shownin FIG. 12E, the Lower Back, as shown in FIG. 12F, the arch of the foot,as shown in FIG. 12G, the Achilles, as shown in FIG. 12H, and the Calf,as shown in FIG. 12I.

The result is therapeutic, fitness and sports enhancement device 10 witha unique combination of one or more of density and diameter and theshape of projections 14 maximizes mobilization of soft tissuestructures. Typical target soft tissue mobilized by the plurality ofshaped projections 14 may include muscles, tendons, ligaments-fascia ofthe human body and the like. Mobilization of soft tissue by projections14 massages soft tissue and breaks up scar tissue. This increasesflexibility of soft tissue, decreases muscle soreness, relieves jointstress, decreases neuromuscular hypertonicity, increases joint rangemotion and extensibility of musculotendinous junctions, optimizes softtissue distensibility, increases neuromuscular efficiency, increasesflexibility and helps maintain normal functional muscle length. Thesebenefits enhance recovery of injuries when used as a therapeutic tool,maximize sports performance, and improved fitness. Device 10 alsooptimizes body core strength and optimizes balance training.

In one example, therapeutic fitness and sports enhancement device 10,FIGS. 1-12I may be manufactured using extrusion process as know by thoseskilled in the art. In this example, raw material in the form ofgranules of plastic, e.g., polyethylene, is put hopper 150, FIG. 13, andfed into heated chamber 152.
